You'll start out in a blizzard. Walk forward and you'll come to a cliff face. When you get there, you'll be taught how to find out where your next objective is. Press the right stick in like a button and wait a moment for the line to appear. The line is the direction you want to go. Walk between the two large rocks.
| SCAF Artifact |
 The path to the left will open up quite a bit and you can follow it to anther cliff wall. Walk along this cliff until you see another rock appear on the right side. In between the two will be your first collectible: The SCAF Artifact. |
If you go the SCAF artifact, you can continue on directly ahead to meet up with your original path. The path will lead you out over a cliff so be careful where you're going! This will bring you to a downed ship. You'll find a door that looks sealed shut. In front of the door will be several crates that you can bust open using your ability to stomp. Grab the ammo, reload and then walk over to the sealed door to open it.
When you try to open it, you'll be attacked by a couple of Necromorphs. If this is your first time fighting them, you want to aim for the limbs to do critical damage rather than aiming for their heads. There's plenty of room to back up to the left if you need the space so keep backing up and shooting, you should have plenty of room.
With Necromorphs, you can stomp on their bodies for loot so take what you can and reload before heading in. Inside, the room will curve to the left and as you turn right, another Necromorph will appear at the end of the hall. Further up the hall, you will encounter another couple of enemies at the end. Move slowly because they may not all appear immediately.
At the end, climb up the ladder. At the top, turn towards the cockpit and enter it to find the Cylinder you were looking for.
Descent
Well that was a mess. Start walking down the side of the cliff. When you come to your first gap, you'll be able to leap over it. Keep leaping over gaps and avoiding the rocks. You'll also see shadows below you indicating following objects so try to avoid them as well.
When you hit the ground, the plane will almost come down on top of you. You'll be sliding backwards across the ground but you still have lateral control so try and roll to the left to avoid the various debris flying at you. If you manage to avoid it all (particularly the large engine) then you'll make it to the end of the chapter.
